Gravity is
rather a special force which is unusual which is different from many other
forces like electrical forces , etc.

And is
somewhere connected with geometric properties of space and time which has a
great impact to the brain of our great scientist Sir Albert Einstien.

Here, in
this post we gonna talk about the working of a great man on two historical
terms.Which was named as………

The
Newtonian Physics

(A introduction to general
theory of relativity)

Ok, now we
know the two terms Newton for which he is really famous for but I would like to
take a part of it and want to reavel the real concepts and story behind the origination
of a historical formula

The universe
is after all is really meant with some basic and complicated topics which needs
a real concepts and that needs a separate space to be studied. Well more over
every single thing want its own identity to be done in this whole universe it
needs its own structure, its own study, its own way of enviromenting and etc.
with all pohilosphical aspects.

The above
paragraph can be summarized by saying-

“Why not to
studythings with respect to the terms
of observing the things particularly with their own philosophical and our sets
of mind”.

Now, as I
said we too want a seprate study to have the knowledge of The grand design of
universe so we too have a different field to study them because even a child
know that theuniverse may be all
about……..

with
structures on a vast range of scales

planets orbit stars

stars are
collected into galaxies

galaxies are
gravitationally bound into clusters

even clusters of galaxies are found within
larger superclusters

and many
more………..

that’s
really confusing I guess.

so in which
field we gonna study this well I guess we got some thing to know more about them
yes, its all about

“Cosmology”

Cosmology is
the study of the universe, or cosmos, regarded as a whole. Attempting

to cover the
study of the entire universe.

The universe
is after all richly textured form its history and till now with its every
minute

And every
seconds. It would have been easy to get every single thing about universe if
this line would have been existing as a truth…………

“The
existence of an idealized perfectly smooth, model universe.”

Cosmology
and Astronomy comes with the same aspects and can be summarized as

Astronomy is
probably the oldest of all the sciences. It differs from virtually all other
science disciplines in that it is not possible to carry out experimental tests
in the laboratory. Instead, the astronomer can only observe what he sees in the

Universe and
see if his observations fit the theories that have been put
forward.Astronomers do, however, have one great advantage: in the Universe,
there exist extreme states of matter which would be impossible to create here
on Earth. This allows astronomers to make tests of key theories, such as Albert
Einstein’s General Theory of Relativity.We will see
how two precise sets of observations, made with very simple instruments in the
sixteenth century, were able to lead to a signifi cant understanding of our
Solar System. In turn, these helped in the formulation of Newton’s Theory of
Gravity and subsequently Einstein’s General Theory of Relativity – a theory of
gravity which underpins the whole of modern cosmology. In order that these
observations may be understood, some of the basics of observational astronomy
are also discussed.

Cosmology binds up all the real concepts existing in the universe which
really not easy to understand the complicity of the term UNIVERSE

A remarkable
fact about the universe we find ourselves in is that it is capable of
sustaining a planet like the Earth and the complex chemistry of life.On this planet we have achieved an understanding
of the vast universe we inhabit, but this has been

achieved
only in the past century. It was only as recently as the 1920s that we began to
get a glimpse of the vastness of the universe of galaxies. The discovery of the
microwave backgroundradiation and the realization that the universe began in a hot Big Bang dates
back only to 1965.

And
it is only since the beginning of the new millennium that cosmology has become
a precision science, with a strong consensus emerging about what kind of universe
we inhabit.

That was all
possible because of the existence of really a wide term named “cosmology”

Now, we welcome the young scientist in the 1920's who is the combination of the great scientists in the past centuries.He is nor other than "EDWIN HUBBLE".

His contributions to our understanding of the universe came in two parts.He was the first to determine by precise measurement the distances of galaxies, establishing that they were great but comparable galaxies in their own right,not objects in the Milky Way.It was pretty cool to listen but it is just a begining.

As i have already said that "universe" is really a complicated topic .I feel that we are very much greatful that we are the one who are part of this earth (the only planet where life exist) and borned here as a human being (the most inteligent creature on earth).And got a chance to know the vast universe. Well every work starts from a basic concepts and we have acheived those basic concepts by the amazing workings of our great scientists in our passed centuries.

It was only as recently as the 1920s that we began to get a glimpse of the vastness of the universe of galaxies.And it is only since the beginning of the new millennium that cosmology has become a precision science, with a strong consensus emerging about what kind of universe we inhabit.lets start our journey of what we gonna talk about............Aristole lived on earth for around 384–322 BC who was the first to estimate the size ofthe Earth, using the angle of the shadow of a pole at noon at a location 100 miles south of the equator.whooo, that was really amazing but the thinking of universe was just started.Eratosthenes and Posidonius took part in the evaluation of searching about universe and used somewhat similar way as aristole did which passed around only 10% in the feild of cosmology.Many thinkers started to give their veiws on the Astronomy and used different methods to know about different distances between two heavenly bodies i would like to pick one of them.Hipparcho, (In the second century BC) used a method---- " solar eclipse method to estimate the distance of the Moon from the earth and deduced a value for earth by giving a value 59 Earth radii, a little under the modern value of 60.3. " well this method was use by aritochoros too. he used this method to estimate the distance of earth by lunar eclipse but was out by a factor of 20.

The next comes the GREEKS with their scholastic minds and gave the euclidian geometry which we students know it very well by "THE EUCLID GEOMETRY" which gave the idea for the ring of modern science and the idea of an infinite physical frame.I would like to share this that medival people use to think tha stars were at a range of distances but according to our new erathe stars are now been calculated to light years it really strikes to be very far. Then the arabic derived.......... "title reflects the crucial role of Arab scientists preserving and extending the achievements of the Greeks."

Well that was not true and was provened by 'NICOLUS COPERNICUS'............was aware of Arab work in his development of a Sun-centred (heliocentric) model of the solar system. A discovery of Copernicus that is less well-known is that he gave, for the first time, the correct relative distances of the Sun and planets. His values were within 5% of the modern values and the absolute scale of the solar system was not determined more accurately till the 19th century. The Copernican system also implied a huge increase in the minimum distance of the stars.

GALILELEO GALILIE the man behind the victory of 'NICOLUS COPERNICUS' as he took the wordings of his and and went against the thinking of the human society. He started his journey by discovery in 1609 of the moons of jupiter lent weight Copernicus’s picture of the planets orbiting the Sun. His discovery of mountains on the Moon showed this was another world like the Earth. And his resolution of the Milky Way into stars was the first step into the universe of galaxies. Galileo’s work on kinematics demonstrated the limitations of Aristotle’s physics and paved the way for the system created by Sir Isaac Newton (Newtonian mechanics) and still used for most everyday situations today. In his interesting dialogue with the philosopher Richard Bentley, Newton also discussed the idea of an infinite universe of stars.
